Description

Technical Field

[0001] This utility model relates to the field of touch screen technology, specifically a touch screen assembly structure. Background Technology

[0002] A touch screen is a device formed on the display surface of an image display device, such as a capacitive touch screen. It mainly consists of a backlight frame, a backlight assembly, a touch screen panel, and a screen frame.

[0003] In full-screen or narrow-bezel display devices, capacitive touchscreens are generally fixed by adhesive bonding to structural components. While this method is simple to assemble, it is difficult to disassemble, and disassembly can easily damage the touchscreen or LCD screen, increasing the scrap rate and cost. According to a capacitive touchscreen reinforcement structure disclosed in patent publication number CN221175394U, the technical solution mainly uses mounting screw holes on the backlight frame to facilitate users to fix the screen frame assembly to the backlight frame with screws. The rear side of the touchscreen assembly and the front side of the backlight assembly are assembled by adhesive bonding. Screen frames A and B lock the two wide sides of the touchscreen assembly, and screen frames C and D lock the two long sides of the touchscreen assembly, pressing the backlight assembly onto the backlight frame. This completes the positioning, assembly, and reinforcement of the touchscreen assembly and backlight assembly on the backlight frame, effectively reducing the scrap rate from disassembly, improving maintenance efficiency, and is simple and easy to implement.

[0004] However, the touch screen of the above-mentioned technical solutions has poor overall sealing performance, making it easy for water and moisture to enter and cause damage to the touch screen. In addition, the heat dissipation effect of the touch screen structure of the above-mentioned technical solutions is not good. Therefore, we provide a touch screen assembly structure to solve this problem. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution for a touch screen assembly structure that can solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a touch screen assembly structure, including a touch screen component and a backlight frame plate, wherein a backlight component is mounted on one side of the backlight frame plate, and one side of the touch screen component is bonded to the backlight component. A square groove is provided on one side of the backlight frame plate, and a screen frame component is snapped into the inner cavity of the square groove. A sealing component is bonded to the inner side of the screen frame component, and one side of both the backlight component and the touch screen component is located in the inner cavity of the sealing component.

[0007] The screen frame assembly includes a heat-dissipating metal frame that is snapped into the inner cavity of a square groove, and heat dissipating fins are equidistantly arranged on the outer side of the heat-dissipating metal frame.

[0008] As a further embodiment of this utility model: two positioning posts are installed on one side of the heat dissipation metal frame, and two positioning holes are provided on the outer side of the backlight frame plate for insertion.

[0009] As a further embodiment of this utility model: the sealing assembly includes a rubber sealing frame bonded to the inner side of the heat dissipation metal frame, and heat dissipation grooves are equidistantly arranged on the inner side of the rubber sealing frame. The backlight assembly and the touch screen assembly are in contact with the inner wall of the rubber sealing frame on one side and all four sides.

[0010] As a further embodiment of this utility model: the inner cavity of the square groove is fitted with a first sealing strip, which is located between the inner wall of the square groove and one side of the heat dissipation metal frame.

[0011] As a further embodiment of this utility model: a mounting groove is provided on one side of the heat dissipation metal frame, a second sealing strip is bonded to the inner cavity of the mounting groove, a sealing groove is provided on the side of the touch screen component corresponding to the position of the mounting groove, and one side of the second sealing strip is inserted into the inner cavity of the sealing groove.

[0012] As a further embodiment of this utility model: the outer side of the backlight frame plate is provided with multiple sets of mounting holes, all of which are connected to the square groove, and the fixing bolts pass through the square groove and are screwed to the heat dissipation metal frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The first sealing strip effectively improves the sealing effect of the insertion between the heat dissipation metal frame and the square groove on the outside of the backlight frame plate. The rubber sealing frame designed inside the heat dissipation metal frame effectively seals the four sides of the backlight component and the touch screen component, preventing water or moisture from entering and damaging the backlight component and the touch screen component during use. Furthermore, one side of the second sealing strip, which is attached to the mounting groove on the outside of the heat dissipation metal frame, is inserted into the sealing groove on the outside of the touch screen component, further improving the prevention of external moisture from entering the touch screen component and the backlight component, effectively improving the sealing effect and protecting the touch screen component.

[0015] 2. Multiple heat dissipation grooves designed inside the rubber sealing frame allow the heat generated by the touch screen component during operation to be quickly absorbed by the rubber sealing frame and transferred to the heat dissipation metal frame. Subsequently, the heat dissipation fins designed on the outside of the heat dissipation metal frame quickly absorb the heat and dissipate it outwards, effectively dissipating the heat generated by the touch screen component during operation and improving the performance.

[0016] 3. After the heat dissipation metal frame is inserted into the positioning hole on the outside of the backlight frame plate through the positioning post, it is convenient to quickly plug and install the heat dissipation metal frame. Then, multiple fixing bolts are passed through the mounting hole and square groove on the outside of the backlight frame plate and screwed to the heat dissipation metal frame, which facilitates the screw-fixed installation of the heat dissipation metal frame and makes it easy to disassemble.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 A touch screen assembly structure includes a touch screen component 1 and a backlight frame plate 2. A backlight component 4 is installed on one side of the backlight frame plate 2. The touch screen component 1 is bonded to the backlight component 4 on one side. A square groove 5 is provided on one side of the backlight frame plate 2.

[0027] The inner cavity of the square groove 5 is fitted with a screen frame assembly 3. The screen frame assembly 3 includes a heat dissipation metal frame 31 fitted into the inner cavity of the square groove 5. Heat dissipation fins 32 are equidistantly arranged on the outer side of the heat dissipation metal frame 31. Two positioning posts 34 are installed on one side of the heat dissipation metal frame 31. Two positioning holes are provided on the outer side of the backlight frame plate 2 for insertion. A first sealing strip 6 is fitted into the inner cavity of the square groove 5. The first sealing strip 6 is located between the inner wall of the square groove 5 and one side of the heat dissipation metal frame 31. Multiple sets of mounting holes are provided on the outer side of the backlight frame plate 2. All mounting holes are connected to the square groove 5. Fixing bolts 9 pass through the square groove 5 and are screwed into the heat dissipation metal frame 31.

[0028] After the first sealing strip 6 is inserted into the square groove 5, the heat dissipation metal frame 31 is then inserted into the square groove 5. The heat dissipation metal frame 31 is then inserted into the positioning hole on the outside of the backlight frame plate 2 through the positioning post 34, which facilitates the quick insertion and installation of the heat dissipation metal frame 31. Subsequently, multiple fixing bolts 9 are threaded through the mounting holes and square groove 5 on the outside of the backlight frame plate 2 and screwed onto the heat dissipation metal frame 31, which facilitates the screw-fixed installation of the heat dissipation metal frame 31 and makes disassembly convenient. The first sealing strip 6 effectively improves the insertion and sealing effect between the heat dissipation metal frame 31 and the square groove 5 on the outside of the backlight frame plate 2. Furthermore, the heat dissipation fins 32 designed on the outside of the heat dissipation metal frame 31 quickly absorb the heat generated by the touch screen component 1 when it is displaying graphics after the touch screen component 1 and the backlight component 4 are bonded together. The heat is then quickly absorbed by the multiple heat dissipation fins 32 and discharged to the outside, effectively dissipating the heat generated by the touch screen component 1 when it is working, thus improving the performance.

[0029] A sealing component 7 is bonded to the inner side of the screen frame assembly 3. One side of the backlight assembly 4 and the touch screen assembly 1 are both located in the inner cavity of the sealing component 7. The sealing component 7 includes a rubber sealing frame 71 bonded to the inner side of the heat dissipation metal frame 31. Heat dissipation grooves 72 are equidistantly arranged on the inner side of the rubber sealing frame 71. One side of the backlight assembly 4 and the touch screen assembly 1 are in contact with the inner wall of the rubber sealing frame 71.

[0030] By using a rubber sealing frame 71 designed inside the heat dissipation metal frame 31, the backlight assembly 4 and the touch screen assembly 1 are further bonded together, effectively sealing the area around the bonded surfaces. This prevents water or moisture from entering and damaging the backlight assembly 4 and the touch screen assembly 1 during use. Furthermore, the multiple heat dissipation grooves 72 designed inside the rubber sealing frame 71 allow the heat generated by the touch screen assembly 1 during operation to be quickly absorbed by the rubber sealing frame 71 and transferred to the heat dissipation metal frame 31. This effectively improves heat dissipation while maintaining a tight seal, resulting in excellent performance.

[0031] A mounting groove 33 is provided on one side of the heat dissipation metal frame 31. A second sealing strip 8 is bonded to the inner cavity of the mounting groove 33. A sealing groove 10 is provided on the side of the touch screen assembly 1 corresponding to the position of the mounting groove 33. One side of the second sealing strip 8 is inserted into the inner cavity of the sealing groove 10. The second sealing strip 8, made of rubber material, is bonded to the mounting groove 33 on the outside of the heat dissipation metal frame 31, while one side of the second sealing strip 8 is simultaneously inserted into the sealing groove 10 on the outside of the touch screen assembly 1. This further improves the prevention of external moisture and other substances from entering between the touch screen assembly 1 and the backlight assembly 4, effectively improving the sealing effect and facilitating the protection of the touch screen assembly 1.

[0032] Working principle: After the first sealing strip 6 is inserted into the square groove 5, the heat dissipation metal frame 31 is then inserted into the square groove 5. The heat dissipation metal frame 31 is then inserted into the positioning hole on the outside of the backlight frame plate 2 via the positioning post 34, facilitating quick insertion and installation of the heat dissipation metal frame 31. Subsequently, multiple fixing bolts 9 pass through the mounting holes and square groove 5 on the outside of the backlight frame plate 2 and are screwed onto the heat dissipation metal frame 31, facilitating screw-fixed installation and easy disassembly. The designed first sealing strip 6 effectively improves the insertion and sealing effect between the heat dissipation metal frame 31 and the square groove 5 on the outside of the backlight frame plate 2. After the touch screen assembly 1 and the backlight assembly 4 are bonded together, the rubber sealing frame 71 designed inside the heat dissipation metal frame 31 effectively seals the area around the bonded backlight assembly 4 and touch screen assembly 1, preventing water or moisture from entering the backlight during use. Damage can occur between component 4 and touch screen component 1. Multiple heat dissipation grooves 72 designed inside the rubber sealing frame 71 allow the heat generated by the touch screen component 1 during operation to be quickly absorbed by the rubber sealing frame 71 and transferred to the heat dissipation metal frame 31. This effectively improves heat dissipation while maintaining a tight seal, resulting in good performance. Subsequently, the heat dissipation fins 32 designed on the outside of the heat dissipation metal frame 31 quickly absorb heat and expel it outwards, effectively dissipating the heat generated by the touch screen component 1 during operation and improving performance. Meanwhile, one side of the second sealing strip 8, bonded to the mounting groove 33 on the outside of the heat dissipation metal frame 31, simultaneously engages with the sealing groove 10 on the outside of the touch screen component 1, further preventing external moisture from entering between the touch screen component 1 and the backlight component 4, effectively improving the sealing effect and protecting the touch screen component 1.
